# macos-control

The `sagui` CLI provides mouse control, keyboard input, screenshot capture, image recognition, and screen queries for macOS automation.

## Preflight: ensure `sagui` is installed

Before issuing any `sagui` command, run:

```bash
command -v sagui
```

If the command prints a path, you're ready — continue to the sections below.

If it prints nothing (exit code 1), `sagui` is not installed. **Stop and ask the user for permission to install it** before doing anything else. Show them these steps and wait for confirmation:

```bash
# Prerequisite: Xcode / Swift 6.2+ toolchain (`swift --version` to verify)
git clone https://github.com/NakaokaRei/SwiftAutoGUI.git /tmp/SwiftAutoGUI
cd /tmp/SwiftAutoGUI
swift build -c release
# Copy the binary somewhere on $PATH. /usr/local/bin requires sudo:
sudo cp .build/release/sagui /usr/local/bin/sagui
# Or, no sudo, into a user dir already on PATH:
# cp .build/release/sagui ~/.local/bin/sagui
```

After install, re-run `command -v sagui` to confirm the binary is reachable, then continue.

## Permissions

The first time `sagui` issues an event or screenshot, macOS will prompt for these permissions. Without them, commands silently fail or return blank screenshots.

- **Accessibility** — required for `sagui key` and `sagui mouse`. Enable in System Settings → Privacy & Security → Accessibility for the app running Claude Code (Terminal.app, iTerm, etc.).
- **Screen Recording** — required for `sagui screen screenshot`, `sagui screen pixel`, and `sagui screen locate*`. Enable in System Settings → Privacy & Security → Screen Recording for the same app.

If a command unexpectedly fails or returns empty output, ask the user to verify both permissions are granted to their terminal app.

This skill is **macOS-only** — `sagui` builds on CoreGraphics. On other platforms, tell the user the skill cannot run and stop.

## Coordinates

All coordinates use **CGWindow coordinate system** — logical points with origin at the **top-left of the primary display**.

- x increases to the right
- y increases downward
- Values are in logical points (not pixels)

Use `sagui screen size` to get screen dimensions.

## Commands

### key — Simulate keyboard input

```bash
sagui key shortcut command c             # Keyboard shortcut (Cmd+C)
sagui key shortcut command shift a       # Multi-modifier shortcut
sagui key down shift                     # Press key without releasing
sagui key up shift                       # Release a held key
sagui key type "Hello, World!"           # Type text character by character

### mouse — Control mouse cursor

Coordinates are **screen points** (origin top-left).

```bash
sagui mouse position                                                  # Print current position
sagui mouse move --x 500 --y 300                                      # Move to absolute position
sagui mouse move-relative --dx 50 --dy -30                            # Move relative to current
sagui mouse click                                                     # Left click at current position
sagui mouse click --right                                             # Right click
sagui mouse click --double                                            # Double-click
sagui mouse click --triple                                            # Triple-click
sagui mouse drag --from-x 100 --from-y 100 --to-x 400 --to-y 400    # Drag
sagui mouse scroll --vertical 5                                       # Scroll up
sagui mouse scroll --vertical -3                                      # Scroll down
sagui mouse scroll --horizontal 2                                     # Scroll left
```

| Subcommand | Required | Optional |
|---|---|---|
| `position` | | |
| `move` | `--x`, `--y` | |
| `move-relative` | `--dx`, `--dy` | |
| `click` | | `--right`, `--double`, `--triple` |
| `drag` | `--from-x`, `--from-y`, `--to-x`, `--to-y` | |
| `scroll` | | `--vertical <clicks>`, `--horizontal <clicks>` |

### screen — Screenshots and screen queries

```bash
sagui screen size                                          # Print screen dimensions
sagui screen screenshot                                    # Save screenshot to screenshot.png
sagui screen screenshot --output capture.png               # Save to specific path
sagui screen screenshot --region 0,0,500,500               # Capture specific region
sagui screen pixel --x 100 --y 200                         # Get pixel color (R G B A)
sagui screen locate button.png                             # Find image on screen (X Y W H)
sagui screen locate button.png --confidence 0.8            # Find with lower threshold
sagui screen locate-center button.png                      # Find image center (X Y)
```

| Subcommand | Required | Optional |
|---|---|---|
| `size` | | |
| `screenshot` | | `--output <path>` (default: `screenshot.png`), `--region <x,y,w,h>` |
| `pixel` | `--x`, `--y` | |
| `locate` | `<image-path>` | `--confidence <0.0-1.0>` |
| `locate-center` | `<image-path>` | `--confidence <0.0-1.0>` |

**Image recognition** uses OpenCV template matching. Default confidence threshold is 0.95. Lower it for fuzzy matching.

### agent — AI-powered automation

```bash
sagui agent "Open Safari and search for Swift"                    # Run with on-device model
sagui agent "Click the submit button" --api-key sk-...            # Run with OpenAI
sagui agent "Fill in the form" --model gpt-5.4 --max-iterations 10
```

| Required | Optional |
|---|---|
| `<goal>` (string) | `--api-key <key>` (or `OPENAI_API_KEY` env), `--model <model>` (default: `gpt-5.4`), `--max-iterations <n>` (default: 20), `--delay <seconds>` (default: 1.0), `--no-screen-context` |

## Workflow

### Screenshot + mouse/keyboard interaction

1. `sagui screen size` — get screen dimensions.
2. `sagui screen screenshot --output /tmp/screen.png` — capture current state.
3. Read the screenshot image to identify target coordinates.
4. `sagui mouse move --x <x> --y <y>` and `sagui mouse click` — interact.
5. `sagui key type "text"` or `sagui key shortcut command a` — keyboard input.
6. `sagui screen screenshot --output /tmp/verify.png` — verify result.

### Image-based interaction

1. `sagui screen locate-center target.png` — find element position.
2. `sagui mouse move --x <x> --y <y>` — move to found coordinates.
3. `sagui mouse click` — click the element.

## Notes

- All mouse and keyboard commands require Accessibility permissions.
- Screenshot and image recognition commands require Screen Recording permissions.
- `key type` supports any Unicode character. Use `key shortcut` with modifier keys for keyboard shortcuts.
- Scroll: positive vertical = up, negative = down; positive horizontal = left, negative = right.
- Image recognition confidence defaults to 0.95; lower for fuzzy matching (e.g., 0.8).
- Supported screenshot formats: PNG, JPG/JPEG, GIF, BMP, TIFF (detected from file extension).
